Today, we live in the era of cloud computing. It can be more popular to say that our life is actually an algorithm. Our existence requires a lot of data, and cloud computing is to integrate and calculate these data. Nowadays, not only do we have the concept of cloud computing but also the concept of sea computing at the same time in our lives, then how much do we know about them.
First, about cloud computingTraditional applications are becoming more and more complex: they need to support more users, they need more computing power, they need more stability and security, etc., in order to support these growing demands, companies have to buy various hardware devices. (server, storage, bandwidth, etc.) and software (database, middleware, etc.), in addition to the need to set up a complete operation and maintenance team to support the normal operation of these devices or software, including maintenance, installation, testing, testing , running, upgrading, and ensuring system security. You'll find that the overhead of supporting these applications is huge, and their cost increases as your application grows in size or size. That's why even in large companies with very good IT departments, those users are still complaining that the systems they use are difficult to meet their needs. For small and medium-sized enterprises, even individual entrepreneurs, the cost of operating software products is even more unbearable.
So, cloud computing came into being - bigger, faster, stronger
Once you've deployed your app to the cloud, you don't have to worry about the hard-hitting hardware and software issues that are addressed by the cloud service provider's professional team. Using shared hardware means using cloud services like a tool (just like plugging in a socket, you can use electricity as easily). You only need to pay the corresponding fees according to your needs. With regard to software updates, the on-demand expansion of resources can be done automatically. More and more enterprises are beginning to use cloud-based enterprise services, and life is undergoing revolutionary changes and changes due to "cloud computing"!
Second, the image point to say "cloud computing"[1] Tap viewpoint:
When you need it, twist the faucet and the water will come. I just have to worry about paying the water fee! When you need to use a software, you don't have to go to Computer City, open the app store, it downloads it, you just have to pay the money; when you want to read the newspaper, you don't have to go to the newsstand, just open Headlines, news is at your fingertips; when you want to read a book, you don't have to go to the bookstore, just open the reading software, find a book like this, read it on your mobile phone; when you want to listen to music, you don't have to run again. Audiovisual shops are struggling to find CDs and open music software to listen to music; cloud computing, like opening different water companies in different regions, without geographical restrictions, excellent cloud software service providers, providing software to every corner of the world Service - just like the clouds in the sky, no matter where you are, as long as you look up, you can see!
[2] è¤æ®µå论论:
A metaphor that is very popular on the Internet: a man looking for a girlfriend or wife is a self-built private cloud. The single-cannon or entertainment to the entertainment venue is a public cloud service. It can be used on demand and can be flexibly expanded. Married men looking for a mistress are Hybrid cloud. This kind of explanation is more suitable for men, and it is usually a little explanation!
[3] Sharing Bicycle - Didi Travel Theory:
Traveling requires a car, cloud computing or cloud service is like sharing a bicycle with a taxi or a special express train. You need to use it at any time, and you can pay by the amount (distance). Buying a car and driving a car is a hybrid cloud. The car is your own. Going out to pay for parking or refueling is equivalent to using a public cloud. Amazon or Microsoft Cloud is almost restricted by the policy in China.
[4] Three meals a day to eat goods:
Hungry to eat, cooking at home is a self-built private cloud, you need to build a kitchen to buy pots and pans, rice, oil, salt, etc. After eating, you need to brush your own dishes and other operations, time and effort; outside restaurants provide Equivalent to the public cloud service, on-demand Hu Haisai eats the checkout and wipes away the mouth, how to arrange the cooking order in the restaurant and speed up the delivery speed is the concept of load balancing and virtualization; please cook to the home to cook A typical hybrid cloud that uses limited public clouds in the case of asset security.
Third, on the sea calculation:It is the new technical concept put forward at the Technology Innovation Conference on August 18, 2009. The essence is to push the intelligence to the front end. The intelligent front-end has storage, computing and communication capabilities. It can collaboratively sense and judge decisions between front-ends in a local scene space, responding to perceived events in a timely manner, and has a high degree of dynamic autonomy. Sea computing provides users with an Internet-based one-stop service, which is the simplest and most dependable Internet demand interaction mode.
As long as the user enters the service demand in the sea, the system can clearly identify the demand and assign the demand to the optimal application or content resource provider for processing, and finally return the result to the user. Compared with the back-end processing of cloud computing, sea computing refers to the front-end processing of smart devices. Every “sea water droplet†in sea computing is every object in the world. They are intelligent and can help to perceive interaction. Hundreds of millions of objects make up the Internet of Things system, just as sea water droplets form the sea.
